Motor driven actuator device with battery backup and charging
A recently granted patent (Publication Number: US11984752B2) discloses a motor-driven actuator device with a unique battery management system. The device includes an actuator motor, a controller, an input for an external power supply, and a battery pack that can selectively drive the actuator motor and be connected to the external power supply for charging. The controller is designed to prevent operation if the battery charge level is insufficient for a complete shutdown event, monitor battery status, and adjust charging current based on temperature to prolong battery life.
Furthermore, the patent details a battery management system for the actuator device, which includes a battery manager, actuator motor, input for an external power supply, and a battery pack. The battery manager prevents operation if the battery charge level is inadequate, monitors battery status, and adjusts charging current based on temperature. It also enables the device to operate normally with the battery in an idle or charging state unless an invalid external power supply or shutdown command is detected, triggering a specific shutdown event. This innovative system aims to enhance the efficiency and longevity of the actuator device's battery, ensuring optimal performance and user safety.
